“…These populations were selected from all grass pea growing administrative regions based on different altitude groups of legume production classified by Asfaw Telaye et al (1994) as low (<1900m), mid (1901-2250 m), high (2551-2550 m) and very high (>2550 m) altitudes. Planting of the populations were carried out in the first week of September at Adet Research Center experimental field in a plot size of 4 m 2 (four rows of 5 m length and 0.2 m row spacing) each, using randomised complete block design (RCBD) in three replications at a seeding rate of 40 kg/ha.…”

ABSTRACT:The study was conducted on 50 landrace populations of grass pea at Adet Research Center, Ethiopia, using Randomised Complete Block Design in three replications to determine morphological variability and character associations. Evaluations were made on plant and yield characters from eight plants tagged randomly from each plot. The data were subjected to Analysis of Variance (ANOVA), heritability, correlation and cluster analyses. Higher mean and CV values were recorded for most of the agronomic traits for populations collected from Gondar region and the higher altitude group (>2500 m) indicating the presence of high genetic diversity in this region and altitude group. Phenotypic coefficient of variation (PCV) was slightly higher than genotypic coefficient of variation (GCV) for all the characters studied signifying that genotypic factors exerted reasonable effect in estimating the variation. The wide difference between PCV (22.4%) and GCV (13.0%) for seed yield per plant indicated the complexity of this trait and the important role of other factors such as environment in influencing yield potential in addition to the genetic factors. The strong positive association of pods per plant, 100 seed weight and primary branches per plant with seed yield indicated the possibility of selecting lines for yield improvement based on these characters at the very early stage of the grass pea breeding program.

“…The country is considered as the secondary center of diversity and also one of the nine major agro-geographical production regions of faba bean (Telaye et al, 1994). The production is mainly concentrated in the high-altitudes of Ethiopia ranging between altitudes 1800 and 3000 m.a.s.l with annual rainfall ranging from 700 to 1100 mm (Telaye, 1988). The study area has a total area of 37,360 ha land from this faba bean and field pea shares 2731 and 2285 ha of land annually, from these crops; faba bean ranks first in pulse crops and considered as the most important pulse crop in the area (Sankura, 2015 personal communication).…”

Field experiment was conducted at Chencha Woreda with the objective of evaluating faba bean varieties for better yield and chocolate spot disease resistance during 2015 main cropping season. Ten improved faba bean varieties and two local controls were evaluated in randomized complete block design (RCBD) with three replications. Field performances of varieties were evaluated for grain yield and yield parameters on sampled plant. Chocolate spot disease severity was recorded following 1 to 9 disease scale and used for area under disease progress curve (AUDPC) calculation. There was significant (P < 0.05) difference among the varieties for yield and resistance to chocolate spot disease. Higher yield was recorded in Moti, Gora and Wolki varieties while low yield was recorded from Hachalu and Degaga. Maximum chocolate spot severity and AUDPC were recorded on Baela, Degaga, Gora and Gebelcho varieties while minimum disease severity and AUDPC were recorded from Tumsa, Moti, Hachalu and CS-20DK varieties with a mean severity of 29.63, 24.69, 25.93 and 25.93%, respectively. Moti, CS-20DK, Hachalu and Tumsa varieties showed moderately resistant to chocolate spot disease severity while Dosha was moderately susceptible varieties. From the result it could be concluded and recommended that varieties Moti, Gora and Tumsa are promising at high lands of Chencha, and may used them in larger plot for identification of adaptable variety.

“…; maruca pod borer, Maruca testulalis; pod-sucking bugs, Anoplocnemis curvipes and cowpea beetle, Callosobruchus maculatus (Fabricius), (Coleoptera:Bruchidea) (Dugje et al, 2009). Cowpea beetle is one of the most economic insect pests of stored legume seeds that causes losses in essential legumes up to 50% such as faba bean, field pea, chickpea and lentil (Ali and Habtewold, 1993;Telaye et al, 1994;Damte and Dawd, 2003;Ali et al, 2006).When the seed moisture content is high , damage starts in the field and reaches to the storage (Ntoukam et al, 2000). If insect pests are not successfully controlled, the damage in cowpea seeds will reach 80-100% (Dugje et al, 2009).…”

Cowpea beetle, Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) is one of the most dangerous insect pests in field and storage. It causes a high damage to the legumes by decreased dietary values, germination and seed weights. Using synthetic insecticides for controlling stored grain pests have a lot of problems for humans and environment. Therefore, the mixing seeds laboratory experiments were conducted to study the efficacy of certain alternative safety compounds against C. maculatus such as Beauveria bassiana, Metarhizium anisopliae, ascorbic acid, boric acid, talc powder and kaolin compared with an organophosphorus nervous insecticide, malathion 1% dust, that recommended in Egypt for controlling stored grain pests. The present results showed that the malathion was the highest toxicity effect against cowpea beetle adults with LC 50(3.89 ppm) after 3-day post treatment. However, the boric acid was the lowest toxicity effect with LC50 (72855 ppm) after 6 days post treatment. The other tested materials showed moderate effects. These results indicate that malathion is still having high effect against cowpea beetle. The toxicity of bio-insecticides (M. anisopliae and B. bassiana) after 6days were more than toxicity malathion 1%dust after 1day.Wheraes, the toxicity of bio-insecticides (M. anisopliae and B. bassiana) increased with increase of period of exposure from 2 to 6 days high rates about 28 times, 31 times, respectively. The findings showed that the tested compounds have a promising insecticidal activity against C. maculatus and can be used as possible alternatives to synthetic chemical insecticides such as malathion for the control of stored product insects.
